Overview

Connect to Autumn through Autumn’s hosted MCP server with an Autumn secret key. The Autumn integration exposes billing, customer, plan, balance, and request-log workflows to agent runtimes through Autumn’s official hosted MCP endpoint.

Connect In Mistle

Open Integrations in the dashboard, choose Autumn, then select Secret key. Enter:

After the connection exists:
  1. Open the sandbox profile that should use Autumn.
  2. Add Autumn to the profile’s integration configuration.
  3. Select the Autumn MCP server.
  4. Save and publish the profile version.
